OBNAHEN'IAL ARTIQLES OF MANUFACTURE AND METHOD PRODUCING THE SAME.

Application filed August 2?, 1936. Serial No. 131,975.

This invention relates to improvements in ornamental articles ofmanufacture and to the m thod of producing the same.

The object of the invention is to ornament articles of manufacture suchas furniture, radio cabinets, musical instruments, etc., by combining apart of such structures, such as a desk top, with an inlaid desi ncomprised of a metal plate containing the desi it- 1 seif and a veneerof wood inlaid in t e design, the desk to in the illustration here ivenforming the ass with which the metal esi n and the veneer will beincorporated. The invention further consists in the 5 method by whichthis article is fabricated as will be hereinafter fully stated.

In the accompanying drawings Figure l-is a plan view of say a desk topwith my invention applied thereto;

Figure 2 is a sectional View; Fi ure 3 is a plan view of the metal plateshowing the design.

Figure 4 is a s set of veneer; Fi ure 5 is an inverted plan view of themeta plate and the veneer;

Fi ure 6 is a top plan view of the veneer and t e design;

Figure 7 is a sheet of celluloid.

Let it be supposed that a desk top is to be ornamented with an' inlaiddesign. Such a top is indicated at 1 in the drawings, as best seen inFigure 1. On this top I mount a sheet of veneer, composed of one or morepieces as may be needed. This sheet is inas dicated at 2.

Before the veneer is ap lied to the desk top the design shown in igure 1is fabricated. This design is -shown in Fi ure' 3 where a plan view isgiven of a'met plate 40 3 having a design wrou ht thereon either by theuse of a die by which to stamp the design on the metal plate or by thewell known rocess of etching the design into the plate. In either casethe late is onramented with the design as clear y seen in Figure 3.

In Figure 4 we have illustrated a sheet.

of veneer of wood re resentative of the veneer that is to be in aid inthe design and to be ap lied to the top of the desk in the example erebeing given. In Figure 5 we have illustrated an inverted plan view ofthe metal plate and the veneer after they have been joined together byone of the ste s of the method. Figure 6 I have shown a top looking downon the veneer wit lan view the. de-.

will take on the appearance indicated in Figure 1 where the top of thedesk is shown w th the design wrou ht in metal and in: laid with woodand t e veneer applied to the top. 7

Thus it will be seen that the article comprises as its base apart of thefurniture or other structure, the wood veneer overlying the top and themetal design late occupying a place between the top and the over] 'ngveneer, with that part of the veneer w ich overlies the tracery of thedesi removed to expose the design, and with t at part of the veneerwhich is over the de ressions surrounding the tracery inlaid own in suchdepressions.

will refer now to my method of roducmg this article, I assume that the(idsk top or other structure to be ornamented has been prepared and isread for the application of the veneer and the esign. The particulardesign having been decided u on it is wrou ht in the metal plate 3 eiter by the use 0 a die containing the design or by the use of thewell-known etching process by which the design can be formed on theplate. This being done the metal plate is treated to a light deposit of.latent celluloid solvent such as camphor Sap plied either b deposit froma volatile so ution or by sub imation) and a sheet of dry celluloid issuperimposed upon the treated metal. Then the'wood veneer which has alsobeen previously treated with a solvent such as butanol, 1s laced uponthe cellouloid sheet which now ies on the metal plate. The metal plate,the celluloid' and t e veneer being now together are placed in a pressand subjected to heavy pressure, such as 800 to 1000 pounds per s uareinch for a period of from ten to fi teen minutes, accompanied by heatapplied to the press so as to pro uce a temperature of from 115 C. to125 C. in the plate, celluloid and veneer.

The result of these steps is depress the veneer into the design to givethe appearance shown in Figure 6 where the veneer is represented ashaving been depressed into the recesses about the trace of the designand to overlie the raised sur ace constituted lilllh ill till

ill

by the traeery. ilnd the same time that is being attected, the solventsand the heat acting on the celluloid will have re duced the tacosthereot to a gummy or sticlr v state, whereby it constitutes a mosteltective udhesive between the rectal plate and the wood veneer.

'lhcn the now composite article is with drawn them the press and thetaco out the veneer ground or dressed oft to the entent necessary toremove the wood trons shove the tracerv ol' the design so us to enposethe design and lenve the wood around the design and in the depressionsbetween the lines out tracer-y.

This condition is shown in the linished product represented in Figure lwhere the design is shown inlaid with the veneer and where the veneerand the metal plate have been united to the desk top Tthe method ofuniting the veneer and the metal plate may be the usual one or unitingveneers to furniture such as by the use ct an adhesive and e. suitablepressure to edect the union of the veneer and the top.

ltgein, the heel; ot the metal plate, in order to prevent any undueencrescence oli' it beyond the veneer surtace, is either dressed ott' toreduce the thickness of the plate so that there will be no appreciableencrescence termed by it, or the plate is originally very thin, say ot athickness of not exceeding or less than that of the veneer itselt,except that part oi the plate which is constituted ot the tracery oi thedesign which, of course, must be thiclr enough to allow the design tostand out in reliet in order that the wood 111E137 be inlaid down in thespaces shout the tracery.

lit will now be seen that-by my method l are enabled to beautitully andcheaply ornainent various articles oi manufacture with inlaid work, andthat the resulting product comprises as the base of the article thestructure to be ornamented, as the dosh top, the hidden metal plate withits design wrought thereon and the veneer, which in port is inlaid inthe design and as to the remainder terms the finished surlace ot' thearticle.

it will be understood that l desire to coin prehend within my inventionsuch noodilicetions as may be necessary to adapt it to varyingconditions and uses.

Having thus tully described my invention what ll claim as new and desireto secure by letters Patent, is:

l. The herein described product, consisttoilette design, and e veneer otwood overlying the article and the plate with the'adhesive intervening,and inlaid in the depressions about the design and removed over thetracerv to expose the design, the wood and rectal being united by abinder 0t celluloid.

3. The herein described method of ornameeting an article ot manufacture,consist ing in preparing the part ot the article to be ornamented toconstitute a base; in coatin the said piece with arsolvent forcelluloid; in tabricating a design on a metal plate; in coating themetal with a solvent for celluloid; in piecing a sheet of celluloidbctween the metal and veneer; in laying in the design a wood veneer bythe application ot pressure; in dressing oil the portions ol' the veneerwhich overlie the tracery ot the design. to expose the design and leaveportions of the veneer inlaid in the depressions around the design; andin applying and securing the veneer with its incorporated design to thesurface oi. the article to he ornamented.

l. 'lhe herein described method of ornainenting an article ofmanufacture, consisting in preparing that part oi the article which isto be decorated; in lubricating a design on a metal plate; in applyingto the plate an adhesive comprising celluloid; in overlaying the platewith its adhesive with a wood veneer; in subjecting these parts topressure and heat to force the veneer into the depressions in the platewhich surround the design and partially bulge the tacery oi the designthrough the'veneer; in later dressing oil those portions 01 the veneerwhich so overlie the tracery to expose the design and leave the veneerinlaid about it; end in applylng and securing the veneer with containeddesign to the surface to he ornamented.
